Continuous Glucose Monitoring System Comparisons

CGM Systems: Features in Common

Like insulin pumps, continuous glucose monitoring (CGM) systems all have certain basic properties in common (see below). But each also has unique features that make them better choices for certain individuals.

System includes a receiver/display, transmitter, and subcutaneous sensor.

Wireless system; radio signals utilized.

Waterproof sensors/transmitters (receiver/display not waterproof).

Require periodic calibration with fingerstick blood glucose readings.

Customizable alarms for high/low glucose values.

Multiple on-screen trend graphs.

Arrows indicate rate & direction of BG change

Mechanical device used to insert sensors.

Sensors typically re-usable; sensor life varies from person to person.

Warmup period at beginning of sensor session.

Some lag time between blood glucose (fingerstick) and subcutaneous glucose (sensor) values.
